[U-Boot] [PATCH 0/3] Introduce TPM driver model and STMicroelectronics ST33ZP24 TPMs

[Christophe Ricard]

Hi Simon,
Thanks for pointing me to the right tree and branch. I missed that :-(.

I will go and look at your on-going work and try to fit our STM drivers.

I will be happy to co-work on this.

Best regards
Christophe
